1080p changed to 1080i

[Smith P.]

Nope.
If you want go into that you should see the stream packets exactly.
1080P doesn't carry interlaced half frames, but full frames.

If you want discuss the details of STREAM and its characteristics you should stick with it. Don't slip into receivers/DVD conversions !

Note, you can do 1080p via component cables too, without worrying about HDCP or handshake, etc., but note not many TV's support it. (My Pio Plasma does)

That is true some TVs support this (most famously many of the Pioneer Plasmas), but you cannont get 1080p via component from Dish. This is only supported via HDMI connection (and as pointed out many times by Smith, P. the HDCP handshake must pass in order to get the programming in 1080p.

 

[Smith P.]

I never had that type of TV and start thinking if you have both connections and your TV did get everything correct thru HDMI, will second Component output use 1080p mode same time ?

 

[Jim5506]

HDFury (green) and HDFury2 (green) convert HDMI to component, and pass HDCP.

I use it on my Sony D50Q CRT projector - super picture. (be sure to buy the power supply because Dish does not have the voltage on it's HDMI to power external devices).

 

[Smith P.]

One small correction - Fury doesn't "pass HDCP", but include own full HDCP support, so TV set could be dumb as a pole.

I have two 2007 year model Sony Bravia's. The Dish Network software which needs to sense if you have 1080p compliant equipment does not recognise my sets. Therefore I am not able to download and view 1080p Dish movies on my 1080p sets.
Kinda funny huh? Like they didn't test Sony's?

What are the model numbers of your Sony sets? If they end in "2500" they are 2006 model year sets that were sold in some stores until recently. Those sets will not accept native 1080p. If the models you have end in 3---, 4---, or are XBR4,5,6,7, or 8 they accept native 1080p.

And again.

There are 1080p in 24/30 and 60 fps !

1080p/60 is not an HDTV format.

 

[Smith P.]

Yes it is ! Read ATSC specs before post nonsense !!!

The original 18 formats for digital tv contained 12 SD formats and 6 HD formats. The HD formats were 1280X720p/ 60, 30, 24 and 1920x1080p 30/24. What was the original remaining 1980x1080 format?

 

[tnsprin]

oh, not again ... 1080p and 1080i are different and provide different stream - practically doubled in time ( omitting MPEG-4/H.264/VC-1 compression details); that's why you can't see broadcasting 1080p channels, only VOD or HD/BR disks.

1080P/24 is capable of and has been broadcast. And it is part of the original ATSC standard. Unfortunately they had some people in the early tests that had trouble (although all receivers/tuners are suppose to be able to handle all 18 ATSC signals). At this point no one appears to be broadcasting it, even though it actually take somewhat less room then the 1080i/30 signal.

 

[Smith P.]

Original - yes, but new proposed will have it.

The different resolutions can operate in progressive scan or interlaced mode, although the highest 1080-line system cannot display progressive images at the rate of 59.94 or 60 frames per second. (Such technology was seen as too advanced at the time, plus the image quality was deemed to be too poor considering the amount of data that can be transmitted.) A terrestrial (over-the-air) transmission carries 19.39 megabits of data per second, compared to a maximum possible bitrate of 10.08 Mbit/s allowed in the DVD standard."

Probably beating a dead horse here ...

1080P24 is 24 frames per second.

1080i60 is 60 frames per second.

Going from 1080P24 to 1080i60 is not just a simple case of doubling the frames.

When you interlace, you show basically show one half of the frame, and then the other half. Therefore you have 24 frames from the start, if you show one half and then the other half you now get 48 frames. You need 60 frames, so your DVR is going to add extra frames in there along the way.

The nice thing is the the source is 1080P24 and so you have the full frame, so the conversion should be really good I would think. I don't understand how your 1080i playback was so bad. The source was a 1080P source and it was stored locally on your DVR. I don't think it would get much better than that.

In layman's terms, from ATSC table 3 DTV signals:
480/640 4:3-60p,60i,30p,24p. 480/704 4:3 & 16:9-60p,60i,30p,24p. HDTV 720/1280 16:9-
60i,30p,30p 1080/1920 16:9 60i, 30p, 24p. 60p was thought of to far in the future and complicated for HD at the time of initiation. There are as I understand it, there are cameras that can shoot 60p/720 today. There seems to be some confusion on interlacing. When TV was adopted in 1947 as black and white tv was progressive imagery. With the advent of color the government said that color tv couldn't take any more bandwidth than black and white. Engineers came up with the ingenius technique of interlacing. Interlacing essentialy transmits 60 fields (not frames) every second. by doing odd lines, then even lines. While these are a part of a total picture one has to remember that there is a 60th of a second time travel between the odd lines and the even lines.

Yes, they are different, but in regard to movies and Blu-Ray where the master is 24fps, there would be no difference between 1080i and 1080p when viewing on a 60hz TV.

1080p24, which is what Blu-Ray and Dish's 1080p VOD are, is only beneficial to those with displays with refresh rates that are a multiple of 24hz (ie 120hz). For everyone with a 60hz TV (most TVs 1+ years old) you can watch the VOD at 1080i (ie failed the Dish 1080p test) and get the best you could ever expect on your display. Of course this does assume the electronics in the display are doing the de-interlacing correctly.

Right now, my Sharp Aquos 42D62U 1080p TV fails the 1080p test with VOD. If Blu-Ray also outputs in 1080p/24, does that mean it won't work with my tv? I was thinking about getting a Blue-Ray player and now am not sure. I got lost in all the technical posts on fps...tried to keep up, but got all lost...sorry.

 

[Smith P.]

If it fail, watch it in 1080i - Dish will sell it to you regardless the test.

This really isn't the forum to get into this question. Try AVS they probably have a list of BR players that are & aren't compatible w/ your TV. Some models do all formats some don't.
